Review on Runclean Replacements Compatible Compare XHFFC600 by Olga Porter

Most of this set is great. The only thing I didn't like was the pre-vacuum felt filter, which doesn't fit properly on the LZ601 and I assume the same is true for the other models. It almost fits, but there's more than enough clearance for dirt to be sucked into the engine. IT'S FIXED - Put a thicker asparagus rubber band around the bottom like the attached picture and it should seal just about, even better than the original.
